The limits of fiction: politics and absent scenes in Susumu Hani’s Bad Boys (Furyōshōnen, 1960). A film re-reading through its script
This text proposes an updated analysis of Susumu Hani’s Bad
Boys (1960) through the director’s theoretical contribution and
the re-reading of his script. This film, made within the limits of
reality and fiction, was instrumental in the cinematic language
of the sixties in Japan. Hani implemented herein a style that he
developed during his earlier decade as a documentary maker
for Iwanami Eiga studios. Hani based his filmmaking method on
a philosophical pragmatism extracted from the practices of an
amateur writing called seikatsu kiroku (life document) that
appeared in the early 1950s. In fact, Bad Boys is a loose
adaptation of Tobenai Tsubasa (Wings that Cannot Fly) an
example of seikatsu kiroku consisting of a compilation of
experiences written by inmates from the Kurihama reformatory.
Hani responded to the demands for a new realism of the time
with this film, which he made collectively with the former
inmates of that reformatory. Additionally, a close analysis of the
script reveals significant ‘absent scenes’ of student
demonstrations, which are similar to those Oshima and Yoshida
used in 1960. This fact evidences Hani’s shared concern with
other filmmakers of the time about the necessities of bringing
cinema closer to topical issues
Seismic exploration at Fuji volcano with active sources : The outline of the experiment and the arrival time data
Fuji volcano (altitude 3,776m) is the largest basaltic stratovolcano in Japan. In late August and early September 2003, seismic exploration was conducted around Fuji volcano by the detonation of 500 kg charges of dynamite to investigate the seismic structure of that area. Seismographs with an eigenfrequency of 2 Hz were used for observation, positioned along a WSW-ENE line passing through the summit of the mountain. A total of 469 seismic stations were installed at intervals of 250-500 m. The data were stored in memory on-site using data loggers. The sampling interval was 4 ms. Charges were detonated at 5 points, one at each end of the observation line and 3 along its length. The first arrival times and the later-phase arrival times at each station for each detonation were recorded as data. P-wave velocities in the surface layer were estimated from the travel time curves near the explosion points, with results of 2.5 km/s obtained for the vicinity of Fuji volcano and 4.0 km5/s elsewhere
Icequakes around Syowa Station, Antarctica
Three types of icequakes were observed by the tripartite seismological network at Japanese Antarctic station, Syowa during the period from February 1976 to January 1977. The types are ; (1) shocks with a sharp initial phase (named Type I), (2) shocks with a small or unidentified amplitude of initial phase (named Type II), and (3) swarms. More than 80000 shocks of Type I and about 80 of Type II occurred through the year. A large number of shocks of Type I occurred in the austral winter season, whereas the number of Type II shocks was larger in summer than in winter. No correlations are identified between the icequake occurrence and the air temperature change, and between that and the sea level change. The features of icequakes suggest that the shocks of Type II are caused by fractures in the ice near the shelf edge of ice sheet, giving rise to the calving of icebergs and so on. Swarms are estimated to be caused by the temperature changes

1976年2月から1977年1月まで,南極・昭和基地の地震観測網で観測した氷震について調べた.見かけ上氷震は,1)立ち上がりの明りょうな記象,2)立ち上がりの不明りょうな記象,3)群発氷震,の3種類に分けられる.このうち1),2)をそれぞれI型,II型とする.I型は1年間に80000回以上も発生しており,冬季に多い.また,これまで観測された氷震が気温の下降時に発生しているのに対し,I型は気温とは無関係に発生している.また,潮汐との顕著な関係も認められない.II型は約80回発生しているが夏に多く,昭和基地の大陸側から到来することから,大陸氷床の崩壊または,氷山生成に伴う破壊と考えられる.3)の群発氷震は,冬季にのみ発生し,その発生時間も,1日のうち気温変化の大きな夜間に集中していることから,熱歪による体積変化が原因であろう.Three types of icequakes were observed by the tripartite seismological network at Japanese Antarctic station, Syowa during the period from February 1976 to January 1977.

Some Practical Problems on the Determination of Magnitude from Duration Time of Oscillation
A relation between magnitude and duration time of shallow earthquakes was derived for Ohmine, the main station of the Hokushin Observatory of Microearthquakes and Crustal .Deformation. Based on the obtained relation, magnitude of local earthquakes can be determined with a deviation smaller than 0.5 from the magnitude of Japan Meteorological Agency. The effect of the following factors on duration time of oscillation was also examined

The Upper Boundary of the Philippine Sea Plate beneath the Western Kanto Region Estimated from S-P and P-S Converted Waves
Although the subduction of the Philippine Sea plate has generally been investigated by using microearthquake seismicity and determining the three-dimensional seismic wave velocity structure, the configuration of the slab in the western Kanto region is not well known because of low seismic activity. To detect the plate boundary, we placed five seismic stations in the western Kanto region. Clear later phases (X1 and X2-phases) were observed between the P and S arrivals. The seismograms of earthquakes occurring in eastern Yamanashi prefecture show a clear later phase (X1) on the vertical component. The X1-phase, identified as the S to P converted wave at the upper boundary of the descending Philippine Sea plate, constitutes seismological evidence for the existence of the Philippine Sea slab to 20km depth beneath the western Kanto region. The S-P converted points are located in a restricted region along the depth direction, however, necessitating analyses of other phases for slab geometry delineation. The seismograms from earthquakes occurring beneath the east coast of the Izu Peninsula showed a clear later phase (X2-phase) dominant on the horizontal components. The observed values of the X2-P time and locations of known velocity discontinuities are consistent with the later phase being a P to S converted wave at the upper boundary of the subducting Philippine Sea plate. The upper boundary estimated from travel time data of the converted wave is located at depths of 28-35 km. Seismological evidence for the existence of the subducting Philippine Sea plate beneath the western Kanto region is shown in this study. The subducting Philippine Sea plate was found to exist at depths shallower than 20km and deeper than 25km from the S-P and P-S converted wave data in the aseismic western Kanto region, respectively. The location of the boundary is estimated to be at depths from 10km to 35km.これまでに,フィリピン海プレートの形状は,震源分布や3次元速度構造のインバージョン等の手法を用いて求められてきた.しかしながら,関東地方の西側地域は地震活動がきわめて低く,その形状を求めることは困難であった
